BBC World Service - Discovery, Frontiers of Earth Science The very latest developments in the world of Earth science with Roland Pease

Didn’t realize that our #AGU25 town hall on Hurricane Katrina 20 year later made the BBC’s Discovery podcast with @peaseroland.bsky.social! Definitely check it out!

This was one of my favorite #AGU25 talks this year

During #AGU25, news broke about the Trump Administration's plans to dismantle NCAR, the National Center for Atmospheric Research. We report on scientist's reactions as the news rippled through the conference, prompting an emergency session. bigpicturescience.org/episodes/col...

Ordinarily pristine streams are turning murky and orange in the Arctic as metals leach out of the rapidly melting ground, killing off local wildlife. We hear from scientists at the #AGU25 meeting about the latest changes to the health of the Arctic region. bigpicturescience.org/episodes/col...

Did you attend #AGU25? Do you have thoughts on how AGQ can improve for AGU26? Do you want to get involved with AGQ behind-the-scenes? Do you want to participate in virtual community-building events with AGQ in February?

Glowing molten ejecta and freshly formed pyroclasts from a submarine volcanic eruption. Two distinct , mildly energetic eruption styles are shown at nearby vents during the 2009 West Mata eruption in northern Tonga. These common but rarely observed fully underwater eruptions produce thick, coarse pyroclastic deposits close to the vent. The deposits are unlike less frequent, but dramatic, very energetic, and more often observed eruptions that break the sea surface, such as Hunga Tonga–Hunga Haʻapai in 2022 or Havre in 2012, with eruption plumes and deposits influenced by distribution all or partly in air. Such eruptions that occur entirely beneath the sea surface produced landforms with low sea bed volcanic terrain stability, impacting the geology, hydrothermal activity, and ecosystem development.

🧪🌋🌊 Deep-sea volcanic pyroclast formation decoded. Most submarine eruptions don't break the sea surface & are rarely observed. We're uncovering how energetic underwater eruptions produce distinctive fragmental deposits unlike subaerial plumes. 2 modes shown here presented at #AGU25. More in ALT text

A digital graphic with a teal background featuring the text “Where Science Connects Us” and the AGU25 logo at the top. A dark blue wavy line runs horizontally across the design behind a photo of a diverse group of smiling people standing in front of an AGU backdrop, with a white AGU sign placed on the ground in front of them. Below the photo, the IGWMC logo and the Princeton University shield logo appear in the bottom left corner.

A 12-photo collage highlighting poster presentations, conversations, and virtual research displays.

An eight-photo collage highlighting oral presentations, set on a teal background. Dark blue squiggly lines intersect and weave between several of the photos, which show presenters speaking and engaging with audiences during oral presentation sessions.

A four-photo collage on a teal background with two dark blue squiggly lines at the top and bottom. The images include a two-tone blue AGU sign, two photos from a group dinner, and a playful group photo at the bottom showing a sillier moment.

AGU 25 — IGWMC edition 🌎
Posters, talks, #hydrology, #machinelearning, community, and lots of great conversations.
So grateful for everyone who made this week what it was.
Already looking ahead to doing it all again at AGU 26!

in case anyone wanted an update, the streak of someone thinking I am a student when I am not at #AGU25 is still alive! This time they thought I was a specific colleagues student. This colleague teaches in Texas and has several Latina students with black hair 😂🤷‍♀️

After Sackett, a Wisconsin-Sized Wetland Area Is Vulnerable  - Eos An analysis of wetland legal frameworks shows how water rules could leave millions of hectares without meaningful protections.

The 2023 Sackett decision weakened wetland protections, and now millions of hectares of wetlands are at risk of being converted or developed, #AGU25 research finds.

The LDEO IcePod—flying aboard a ski-equipped LC-130 Hercules transport aircraft just 1,500 feet above the Ross Sea in Antarctica—imaged and mapped sea ice and glaciers as part of the NSF-funded ROSETTA-Ice Project, which furthered our understanding of the ice, the ocean, and the underlying bed of the Ross Ice Shelf.

✈️ Back from #AGU25!

#CRC1502 #DETECT shared new results on (i) land-surface parameter estimation + reanalysis (Haojin Zhao, D03), (ii) snow data assimilation improving snow states and water/energy fluxes (Buliao Guan, C04), and (iii) gamma-radiation soil-moisture accuracy (Sonia Akter, A02).
